Clinical analysis of fracture of femral shaft in 73 cases treated at the 17 Army Hospital during the period from May 1965 to July 1968 is presented. 1) All the patient were males and in the 3rd decade of life. 2) Sites of fracture were 28 in midshaft, 23 in lower one-third, 22 in upper one-third, and 29 cases: had open fracture. 3) 32 cses(43.8%) were injured by traffic accident which is the most common cause in this series. 4) Conservative treatmet was given in 30 cases, plate fixation in 15 cases, and Kuentscher type of I.M. nailing in 28 cases. 5) Criteria evaluating the results were; knee joint motion, length & alignment of the femur, and pain during weight bearing. 6) Severely comminuted fracture tends to deserve conservative measure only and sites of fracture contraindicated for I.M. nailing were best treated by plate or screw fixation. 7) A comparison has been made between the functional results treated by conservative method and open reduction (plate & screw fixation and I.M. Kuentscher nailing). Excellent or good results were obtained, by conservative (30 cases), plate and screw fixation. (15 cases), and I.M. Kuentscher nailing(28cases), in 46.7%, 60%, and 60.7% respectively. Functional results were slightly better in I.M. nailing than the other two methods. 8) Time of complete healing by solid bone union was; 6.5 months in (30 cases of) conservative treatment, 6 months in (10 cases of) plate and screw fixation, and 5.5 months in (22 cases of) I.M. Kuentscher nailing. 9) Postoperative infection rate,severe enough to interfere healing) was 6.6% (only one case) of plate group and 3.6%(only one case) of I.M. nailing group.

PURPOSE: The purpose of this study was to evaluate clinical manifestation, etiology and prognosis of hypocalcemic infants who were admitted with seizure. METHODS: We reviewed medical records of 32 infants admitted at the Asan Medical Center with hypocalcemic seizure retrospectively. We classified patients into vitamin D deficiency group(n=7, 21.9%), transient hypoparathyroidism group(n=4, 12.5%), relative hypoparathyroidism with hyperphosphatemia group(n=16, 50%), and others(n=5, 15.6%) according to the laboratory results. RESULTS: Of the 32 patients, 29 patients were improved. There were no differences in gestational age and birth weight among the three groups. In the vitamin D deficiency group, age of onset was later than those of the transient hypoparathyroidism group and relative hypoparathyroidism with hyperphosphatemia group(51.6+/-2.7 vs 8.3+/-.5, 8.2+/-.6 days). In the age when all laboratory results were normalized, transient hypoparathyroidism group was younger than those of vitamin D deficiency group and relative hypoparathyroidism group(33.2+/-4.6 vs 93.6+/-8.5, 77.1+/-2.4 days). In the total treatment period, relative hypoparathyroidism with hyperphosphatemia group was longer than those of vitamin D deficiency group and transient hypoparathyroidism group(68.9+/-3.5 vs 42.0+/-5.0, 25.0+/-4.3 days). Others included two 22q11.2 deletion syndrome patients, a congenital hypoparathyroidism, a pseudohypoparathyroidism, and an early neonatal hypocalcemia. CONCLUSION: Transient hypoparathyroidism and hyperphosphatemia were major causes of neonatal hypocalcemia. And high calcitonin and peripheral organ resistance to parathyroid hormone act on hypocalcemia. In infants after one month, vitamin D deficiency was also an important cause of hypocalcemia. Most of the patients were improved within 1-2 months after proper management, but relative hypoparathyroidism with hyperphosphatemia group needed longer treatment. So, it is necessary to perform a systematic study for several complex causes that explain above fact.

Relining and rebasing are essential for long-term success and oral health in removable prosthodontics. Major features of failures between metal base and relining resins are adhesive failure due to lack of chemical bonding. The purpose of this study was to find a better metal primer and metal surface treatment method that enhance the bonding strength with relining resin materials. The surfaces of ticonium alloys were treated with 25micrometer sandblasting (Group A), stone wheel (Group B), stone wheel and EZ oxisor (Group C), 75micrometer sandblasting (Group D) and EZ oxisor application after 75micrometer sandblasting (Group E). They were subdivided into no primer application (Group I), MR bond application (Group II) and Metafast bonding liner (Group III). Then specimens were completed though being bonded with relining resins. The specimens were stored in 38degrees C water for 48 hours and tensile strength was measured using the universal testing machine. The results were as follows, 1. Primer application groups showed higher bond strength than no primer application group(p<0.05). 2. In comparison with primer application groups, MR bond group showed higher bond strength than Meta fast bonding liner application group(p<0.05). 3. In comparison with surface treatment methods. Bond strengths of group A and B were significantly different with group C, D, and E, and group C were significantly different with group D, and E in no primer application group(p<0.05). In primer application groups, group A, B, C were significantly different with group D and E(p<0.05). According to results of this study, Metal primer application and metal surface roughening were considered to be advantageous for relining of metal base dentures.

Background: There have been many reports on microbial contamination of antiseptics and disinfectant used in the hospitals. Mid to low level disinfectants such as chlorhexidine gluconate, quaternary ammonium, phenols and benzalkonium are reported to be the one with high risk of microbial contamination. We investigated microbial contamination of 0.05% chlorhexidine gluconate solution used in our hospital. Methods: 0,05% chlorhexidine gluconate solution and 0.05% chlorhexidine gluconate cotton balls used in the general ward and intensive care unit were randomly collected for microbial culture. Also, sterile water, 20% chlorhexidine gluconate and staining solution, which is mixed in the preparation room to make 0,05% chlorhexidine gluconate solutions, were collected for bacterial culture to evaluate the focus of microbial contamination. Results: Total of 31 chlorhexidine gluconate samples was randomly collected from general wards. intensive care unit and preparation room for microbial culture. Seven of thirteen 0.05% chlorhexidine gluconate solution and 5 of twelve 0.05% chlorhexidine soaked cotton balls kept in a canister were contaminated by Burkholderia cepacia. Sterile water used for dilution of 20% chlorhexidine gluconate to make 0.05% chlorhexidine and originally purchased 20% chlorhexidine gluconate were not contaminated by microorganism. But staining solution that is used as an additive to differentiate from other diluted disinfectants was contaminated by Bukholderia cepacia. 0.05% chlorhexidine gluconate solutions that were mixed in the preparation room were also contaminated by same organism. Source of contamination was thought to be staining solution. All the previously made chlorhexidine. solutions and staining solution were discarded. Staining solution was not used afterward. Several processes in the handling of chlorthexidine solution were corrected and no microbial contamination was found afterward. Conclusion: Diluted chlorthexidine gluconate solutions are always under a risk of microbial contamination if any of the process in the handling is overlooked. Staining solution as an additive to disinfectants should be used carefully.

BACKGROUND: Induction of general anesthesia with tracheal intubation and skin incision are potent stimuli that can induce increased sympathetic activity, heart rate and blood pressure. We compared the hemodynamic response and catecholamine concentration during general anesthesia with intravenous clonidine pretreatment, a centrally acting -2 adrenoceptor agonist, and without pretreatment. METHODS: Forty ASA I or II patients aged from 20 to 60 years undergoing elective surgery were randomly allocated to two groups. In group I, 5 ml of 0.9% normal saline as control administered intravenously 10 minutes before induction of anesthesia, and anesthesia was induced with thiopental sodium, succinylcholine and maintained with N2O (2.5L/min)-O2 (2.5L/min)-enflurane (1.3~1.8 vol%). In group II, 4 g/kg clonidine diluted in 5ml of normal saline administered intravenously 10 minutes before induction of anesthesia, and anesthesia was induced with thiopental sodium, succinylcholine and maintained with N2O-O2-enflurane (0.5~1.0vol%) and 2 g/kg/hr clonidine was continuously infused. We measured blood pressure, heart rate and plasma catecholamine at preinduction, 1 minute after intubation (T1), 1 (T2) and 30 minutes after skin incision (T3) and compared with group I. RESULTS: There was statistical significance in systolic and diastolic pressure at T1 between two groups. There was statistical significance in heart rate, epinephrine and norepinephrine at T1, T2 and T3 between two groups. CONCLUSION: The elevation of blood pressure, heart rate and plasma catecholamine accompanying tracheal intubation and skin incision may be prevented by administration of intravenous clonidine.
